The damping device 3 is located between the leg positioning member 1 and the slide rod 2 so that when the leg positioning member 1 is moved relative to the slide rod 2 to compress the damping device 3, the damping device 3 provides a force to return the leg positioning member 1 and the slide rod 2.

Each handle 4 has a contact member 41 and the two contact members 41 of the two handles 4 are located symmetrically relative to axis of the contact member 41. Each handle 4 comprises the contact member 41 and a grip 42. The contact member 41 has an insertion hole 411 at the rear end thereof and the grip 42 is inserted into the insertion hole 411. The two contact members 41 are located overlapped when viewed from the horizontal direction, so that the grips 42 can be separated from the contact members 41. A locking device 5 is connected to the handles 4 to set the handles 4 to be pivotable or not.

As shown in FIG. 3, the slide rod 2 extends through the passage 11 and the two handles 4 are pivotably connected to the top cap 21. The contact members 41 are located in the end piece 222 of the inner tube 22. The leg positioning member 1 is connected to the inner tube 22 by the connection lugs 221 of the inner tube 22 so that the leg positioning member 1 and the inner tube 22 are co-movable relative to the slide rod 2.The base 24 and the positioning rod 241 are fixed to the slide rod 2 and the damping device 3 is located between positioning tube 223 and the positioning rod 241. The leg positioning member 1 and base 24 of the slide rod 2 can compress the damping device 3 to allow the leg positioning member 1 to be moved back and forth along the slide rod 2. The exerciser is compact, light and easily to be carried and stored.

As shown in FIGS. 4 to 6, the user 7 sits in the chair 8 and the thighs 71 clamp the leg positioning member 1, the hands hold the handles 4. The user 7 applies an upward force to the handles 4 to pull the slide rod 2 upward, while the inner tube 22 and the leg positioning member 1 are stationary by the thighs as shown in FIG. 5, so that the base 24 compresses the damping device 3 which generates a force to against the upward force from the user. The hands are then released, the damping device 3 return the slide rod 2 and the handles 4 to their initial positions a shown in FIG. 7. By repeatedly operation the handles 4, the user 7 is exercised.

As shown in FIGS. 8 and 9, the thighs 71 clamp the leg positioning member 1 and the locking device 5 is operated to unlocked status, the hands hold and pivot the handles 4 to a desired angle. The two respective extensions 412 of the contact members 41 of the handles 4 contact the inner tube 22, while the inner tube 22 and the leg positioning member 1 are stationary by the thighs. The top cap 21 and the slide rod 2 are pulled upward as shown in FIG. 8. The base 24 compresses the damping device 3 which generates a force to against the transverse force from the user. When the slide rod 2 is pulled to the upper most position, the hands are then released, the damping device 3 and the torsion springs 212 return the slide rod 2 and the handles 4 to their initial positions. By repeatedly operation the handles 4, the user 7 is exercised.

As shown in FIGS. 10 and 11, the grips 42 are separated from the contact members 41 and respectively inserted into the through holes 243 of the base 24 of the slide rod 2. The exerciser is then put up-side-down on the thighs of the user 7. The top board 13 of the leg positioning member 1 contacts the thighs 71 or the thighs 71 clamp the leg positioning member 1 (not shown), the hands hold the handles 4 and the elbows are close to the user's body. A downward force is applied from the hands and the upper body of the user 7 to push the handles 4 and the slide rod 2 downward as shown in FIG. 12. The base 24 compresses the damping device 3 which generates a reaction force to the base 24 to fight against the user's force. When the hands are released, the damping device 3 returns the slide rod 2 and the handles 4. It is noted that, as shown in FIG. 13, a pad 10 is used with the exerciser and has a central hole 101 and a connection portion 102 is located on the pad 10. The connection portion 102 is engaged with the leg positioning member 1. The top cap 21, the contact members 41 and the locking device 5 are located in the central hole 101 of the pad 10 which is put on the thighs 71 of the user 7 so as to buffer the impact from the exerciser to the thighs 71. The exerciser exercises the user's hands, legs and upper body including muscles of the arms, abdomen, waist, and chest.

As shown in FIGS. 14 and 15, for convenience of operation of the user 7, the locking device 5 is connected to the top cap 21 and comprises a knob 51, a T-shaped bolt 52 and multiple nuts 53.
